STOP MECHANISM FOR SLIDING ELEMENTS 0F FURNITURE Filed April 15, 1950 INVENTOR. Eda/aria. Fadmarz A ITO/7N5 Y Patented June 10, 1952 UNITED STATES PATENT QFFICE o STOP MECHANISM FOR SLIDING ELEMENTS OF FURNITURE Edward G. Rudman, Nashua, N. H. Application April 13, 1950, Serial No. 155,725

3 Claims. (01. 211- 13) This invention relates to a slide stop for the sliding element or elements of furniture.

Many articles of furniture such as desks, tables, and cabinets of various types, are provided with sliding elements which may consist of extension leaves or rests, and/or drawers or.

bins; and frequently the construction is such that the sliding element may be extended from either of the opposite sides of the article of furniture of which it forms a part.

The object of the present invention is to provide a stop for limiting the extension of the sliding element in either direction.

A further object of the invention is to provide a stop as mentioned which will not stick or bind, work loose, or otherwise get out of order irrespective of atmospheric conditions.

A further object of the invention is to provide a device of the class mentioned which cannot accidently lock the sliding element either in extended or retracted position.

Other objects of the invention are to provide a device as mentioned which shall be quiet in operation, and which needs no adjustment or care after initial installation.

Other objects will appear hereinafter.

With the above objects in view, the invention consists generally in an article of furniture, a sliding element therein adapted to be extended from opposite sides of said article of furniture, said element having a groove in the under face thereof extending parallel to the direction of movement of said element, and terminating at each end in a stop shoulder, a dog pivoted below and adjacent said sliding element and having a free end adapted to be moved into said groove in the path of said stop shoulder, and means actuated by the. movement of said'sliding elements to move said dog into operative position.

The invention further consists in various details of construction and arrangements of parts, all as will be fully described hereinafter and particularly pointed out in the claims.

The invention will be more readily understood by reference to the accompanying drawings forming a part of this specification, and in which:

Fig. 1 is a vertical longitudinal section of a table equipped with a sliding extension element adapted to be extended from opposite sides of the table, and illustrating, in full lines, the element extended from one side of the table, and in dotted lines as extended from the opposite side thereof, the section being taken on the line II of Fig. 2;

Fig. 2 is a bottom plan view of the device as illustrated in Fig. 1;

Fig. 3 is a detail transverse section on the line 33 of Figs. 1 and 2; and.

Fig. 4 is a detail view of the grooved face of the sliding element.

Referring to the drawings, I0 indicates the top of a table, II and I2 the opposite sides of the body of the table, and I3 the legs thereof. The upper edges of the sides II and I2 are recessed as at I4 to receive a sliding extension element I5; said element being provided with a groove I6 in its under face and extending longitudinally of the slide, that is in the direction of movement thereof. The groove I6 terminates short of the ends I! or I8 of the slide forming abutment shoulders 19 and 20, respectively.

Pivotally mounted, as ontranverse pins 2|, adjacent the grooved face of the slide I5, and adjacent the sides I I and I2 of the table are similar stop dogs 22 and 23 respectively. The dogs 22 and 23 extend inwardly from the pivot pins 2I and are adapted to be swung upwardly to project the ends thereof into the groove I6 and into the path of the shoulders I9- and 20.

Rigidly connected to the dogs 22 and 23 are actuating arms 24 and 25, respectively, which are laterally offset therefrom and adapted to engage the adjacent under face of the slide. The dogs 24 and 25 are angularly fixed to the dogs 22 and 23, so that'when the ends of the arms are in engagement with the face of the slide, the dogs will be projected into the groove I6.

In the construction illustrated in the drawings, the dogs and their respective actuating arms are mounted between strips 26 extending between the sides I2 of the table, and preferably close under the slide; the pins 2I having their bearings in said strips.

The operation of the device is as follows. When the sliding element is retracted, that is, within the body of the table or other article of furniture with which the device is used, the ends of the arms 24 and 25 engage the adjacent face of the slide I5 and thereby hold the ends of the dogs 22 and 23 within the slot l6. Should.

the slide I 5 be extended to the left as illustrated in full lines in the drawings, the stop shoulder 26 will engage the end of the dog 22 thereby stopping further extension of the slide I5. Should the slide be retracted and then extended from the opposite side of the table, the shoulder I9 will engage the dog 22 and depress the same below the face of the slide, at the same time raising the end of the arm 24 above the level of said under face; This is possible in that the end of the slide with the abutment 19 will have passed inwardly beyond the arm 24. During the movement of the slide to the right, as above stated, the end of the slide adjacent the shoulder 20 will engage the arm 25, depressing the same to the position shown in dotted lines Fig. 1, and raising the endof the dog23 into the *groove IS in position to be engaged by the shoulder I9.

It is obvious that a stop mechanism as above described will be silent in*operation will not vention is applied may be either portable 'or a permanent fixture. ,2; n lt is to be understood 1 .that variousidetails construction and arrangements of. parts maygbe in'ade without' departing(from :the scopesofethe "invention ems-described and within the scope tli appended claims.
